TCW220 has two analog inputs, with 10-bit resolution and two discrete inputs. It supports a 1-Wire interface for up to eight Teracom 1-Wire sensors – carbon dioxide, 0/20mA, AC/DC current, temperature, humidity, etc.

All monitored parameters can be logged on previous set time intervals and/or on alarm conditions. The memory is large enough for at least 36 days with records recorded every minute, up to 70,000 records. The log file can be periodically uploaded on a dedicated server using HTTP Post.

The relays can be activated either remotely (WEB, SNMP, HTTP, MODBUS TCP/IP, etc.) or locally – providing status of monitored parameters. For every parameter, email and SNMP trap can be sent to up to five recipients. Alarm alerts also can be sent by HTTP Post with XML/JSON status files.
